flhe'nsual platen-coniuge 35 runs upon the rear mil mul front mil 37, n roll 3S being provided tn run upon the lauter. A motor 39 drives the mrriage in both di .reelionrt mid motor having n'n'nrmnture 40, which is The lowenend of the ofthe typgbnr; nd the movement o thecore in the I 'Solenoid sfrelutively ehortf As'see'n at'Fig. 8 the solenoids 19 me electrically eon-l by'wires 24 with contacts 25 beneath the kgy-j levem26fpf theFig. 2 machine. v Thesingle'wire 27, i Fig/8,- connects all of the solenoids to a buttery or monroe of power 28, and-a wire 29 connects the latter to the nietollie. framework of-the Fig. 2 typewritin mo-y The levers 26 are metnLand have metallic con- 'fmme 30, so that depression ofalnylke'y com-' 31 'extending I aitembelyforw'ald and bnelewnrd lfrom the 'middle poi- Asi mirally wound at 41', Aso that it produces a-substan- ,.uy uniform p'ull or torque,'and hence a uniform pull is exerted' upon the carriage. Said armature isconnected by bevel pinions 4.2 43 to a shaft 44, carrying' a spool 45 beneath the system of solenoids 19. `Oppositely'yround cables 46, 47 entendhorizontally in.oppo.

.site directions fr oinlsaid spools l and around pulleys '.48, 49, to the p aperearriage 35. The pulleys4'8, 49 are mounted on hangers 52, dependingfrorn the platen 11.- and the pulleys 50, 51, are mounted opposite the sides of the machine and extend horizontally inward therefrom to operate the carriage. T he cable 46 pulls the carriage in'letter feeding direction while the cable 47 unwirrds from thespool-45. When the rotation of the 15,. latter is reversed,- the cable 47 returns the carriage to 'A begin s'. new line while the cable 4G unwinds froml the spool. From the pulley 50,v cable 46 extends inwardly and terminates ina`wir'e hook or'loop 46",' the latter pivoted at 53 to the usual spacing lever 54, which usually '20 operates a slide 55'having a pawl 56 to engage a ratchet V 1 5712:)` line-space-.the platen 4.. The end of the other doable' 47-has a` hook. 58 caught in said wire loop 46, so

'that therst'pull upon thecable 47`causes a movement '1. oi-tlre lever 54 tothe right at Fig. 6, thereby partially *rotating the platen. This' movementjo the lever is ,lirnited'by the usual stop which is indicated diagram- I* maticlly at 59Fig. 1, in thepath of the slide 55. Continue'd upon `the cable 47-returns the carriage to l ajnewline'. At' the completion ofthe return 30 movement oithe "carriage, the pull upon the cable 47 is -`glrelax'ed, and the linefspacing mechanism is' returned to g no rrnalposition by the Ausual spring' shown ding-ram 5': 'matically at 60, Fig. l.' Moreover the .shiftingof the 'pole-changer 72 to reverse the travel of-the carriage,-

.produces a`pull upon Athe cable 46, thus drawing the Astiff .46! to the left ,and restoring the lever 53 'Y ,to normalfposition.

The field 70 .of the motor are connected by' wires 71,' 72,' 27, 29, t thebnttery 28. In the branch 72 of the circuit is inr`uded a'pole-changer 73 to control the flow of current` i wires 74, 75 leading to the armature40.. By shift' thepolechangen the armature is caused to`rotate in -either-one direction ortho other, so as impel lth'e paper carriage'35 either forwardly or 445- bakwardly-.s desired. It will be understood that when theline is being written, the battery 2,8 operates the 'r'notor between operations of the type-actions, so

that the'ntire current is' available for cach operation.

By screwingin the plug 23 for about one-fourth of .the

length of the solenoid, and making the core or plunger' 60 points of lconnection of the cores to the levers; but the core in web instance nearly touches the plug 23 at the completion ofthe printing stroke. and the shortest'- stroke cores, being always ncar'the plugs, exert a strong pull throughout the .st-nuke, so that the effect upon the l type-bars is about the same as with the langst-stroke cores. About thr'eefourths of the'length of 'the core is within the solenoidkat thecompletion of the printing stroke.

1n said Undertvoo machine,` it is usual to shift the platen up' and down. Normally it is in its lower position', Fig. 1` so as to enable the lower case types 2 to print; and it may be shifted up, Fig. 4', to enable the upper case 'types' 1 to print. platen is usually mounted upon a. shifting frame 76 connected to. the carriage 35 and having a roll 77 to run upon.' a transverse horizontal rail.78 parallelwith the rail 36.' Said 78 is mounted'upon a pair of elbow.

levers 79 'fixed upon a. rock shaft 80. A platen shift For this purpose the.

lever81 having a key 82 and fulcrumed upon the' usual f tulcrum rod 835 is provided with an opstanding arm 84' to engage the rear vertical edge 79" of the elbow lever 79, so that depression of the lever81 locks the lever 79, I

and elevates the shift rail 78 together with the platen, F ig. 4. Accidental displacement of the platen frame when shifted either up or down isiprever'ited by a bar or lever S5 having rear and forward notches 86,87, the

former normally engaging a pin 88 project-mg laterallyfrom the low'erend of the elbow lever 79. The lever .'85-is pivoted at S9. At a point forward' oimid pivot -it is connectedby a lirk 90 to the core 91 of u' solenoid 92, Fig. 8connectedat'one end 'to tlievire 27 and atthe other e'nd 'by a wire 93 toa contact 94. A shift key or lever u pon the oferatorsmachine,-Fi"s 2 and 5,

has a pair of knives 96 forking an insulation block 97, in

which said contact 94 is mounted, said knives 96 being normally above said contact, -Fig. v2. At the first. -pa'rt of the depression of the key 95the knives vS16-engage the contact 94 thereby closing circuit througbthe selen;

oid 92, and vibrating the rear end of lever 85 up torelease the'pin88 and shift lever 79.-. As said key 95`is" pressed farther down, said' knives' 96 engage a lower Contact 98 in said block 97, which is connected through to the wire 27, Fig. 8. The solenoid 100 is connected by a link 101 to the shift lever 81, Fig. l, so that immediately uponl being released from the locking lever 85, the platen .frame and platen are shifted up to positions seen at Fig. 4. The operators shift key 95 is depressed still further, so as tobecome disengived from 'the lower conta-:t 98, Fig. 5, so that 'the entire :flow of solenoid 19 for actuating a type bar 3, :is at Fig. 4

.a wire 99 with a solenoid 100, the latter also connected '11o electricity from .the battery 28 may pass through-any l During the downward movement of the key 95, contact' is brokenbetweeir the knives 96 and the terminal 94,

and a spring 102 'retums the locking lmr 85 to normal position with its forward notch 87 engaging the' locking pin 88, so as to hold the platen frame mechanically in its upper shift position, so that tbe energy of the,

battery 2,8 is not drawn upon for this purpose. While the key 95 is held doufn by the operator, as many type bars Amay be operated as desired. Upon release of .the key 95, it is returned by one of theuslml-lcver springpl 103,:rnd on its upward movement first effects an iille closing movement of the circuit through the solenoid 100, and continuing upward closes circuit through a 'solenoid 92 thereby again releasing the locking pin S8 and 'releasing tbesbift arn1' '!,so that the plutenfr'ame gravitates lou-normal position.

The paper carriage 35 is nl course provided withlthe usual csczqwrin-nl mechanism, a lmrtion of which is l-8os,soo 3 A seen at 104 in the form' of anniversal bar which isop-- eratcdby a heel'10 5 VIci-mod upon the type bals.

Any number of Writing machines may be electrically connected and all operated simultaneously from one operators machine or keyboard. For-this purpose, all

of the selrnoids for the same type or letter may be connccted in series. The motors may also be connected in series so as to be controlled by the same pole-changer. The shifting solenoids may be connected in series, i0, and so lmay be the magnets which release the shift-lock. lf desired, however, the several mechanisms may be. -elebtrcally connected in parallel.

Variations may be resorted to within the scopeoi the invention, and' portions of the improvements may be 1 lused without others.
